Jadavpur University

Go for WBJEE exam. Go to website SEE all the news regarding exams, apply for this exam and if you get good marks then only u will be getting CSE in jadavpur university. If you have a domicile of west Bengal you will be getting the preference I. e 85% reservation for Bengal domicile, and if you are a outsider means if you don't have a domicile of Bengal then my dear you need to work very hard to get CSE and that too in jadavpur university. Its difficult but not impossible. Best of luck for your exams.

If you have confident you can fo better. Then you can wait. But if you haven't enough confidence or you have confident but now you can't give the same effort or time on study. Then you should apply for WBJEE counseling. But some of my experiences said that it's very hard for a person after 10+2 exam to give same effort on study as he/she gave previous. And due to corona everyone faced problem. So now this is depends on you. If you heart say 'Yes I can do' then wait otherwise WBJEE Isn't a bad option.
